Systematic data collection and analysis techniques were used in Los Angeles to discover older adults’ shared explanatory models (EM) of the causes, prevention, symptoms, treatment and consequences of late life illnesses, including influenza and the common cold. Recorded narratives also were analyzed to illustrate similarities and differences in shared cultural knowledge of these illnesses. Consensus analyses results suggest that shared EM of influenza and the common cold are similar. Participants identified both illnesses as contagious, caused or exacerbated by bad weather, but not the result of lifestyle, aging or heredity. Other shared cultural knowledge includes that both illnesses can be treated with home remedies, over-the-counter medications and medical care;both illnesses cause discomfort but are not serious, life-threatening or disabling. Despite the similarities and the apparent merging of the two illnesses in popular thought, many older adults do distinguish them, based on symptom patterns and severity, as revealed in their transcribed narratives. Consistent with other studies, participants attribute gastrointestinal symptoms to influenza but not to colds. They do not understand the potential role of lifestyle, age and chronic conditions in etiology and onset, and they are not concerned with their vulnerability to the potential sequelae of influenza. Public health education explaining the effects of lifestyle on susceptibility and vulnerability to the flu, how to distinguish and appropriately treat colds and the flu, and when to contact physicians, is recommended for older adults. Mixed method studies can prove useful at the planning stages of such interventions. 展开更多

Objective:To elucidate the perceptions of young Chinese adults aged 18–25 toward adopting breastfeeding in public in Hong Kong Special Administrative Region(Hong Kong),China.Methods:A descriptive and exploratory study design was adopted.Participants were recruited by convenience sampling.Focus group data were collected from three semi-structured interviews.Responses from 18 participants were audiotaped,transcribed verbatim,coded,and analyzed using content analysis.Results:Four themes emerged that described the young adults’perceptions and barriers toward breastfeeding practices:(1)adaptability of self and others,(2)cultural deem and practice,(3)convenience and connection,and(4)education and advocacy.Interestingly,all respondents(male and female)are aware of the benefits of breastfeeding.Their negative perceptions toward breastfeeding initiation and continuation originate from factors that are essentially extraneous to the mother-infant dyads(such as the breadth and intensity of sociopolitical support,the dominant social beliefs and norms,and the inadequacy of breastfeeding education in adolescent years).Conclusions:In general,the young adult’s perception of breastfeeding is dominated by sociopolitical and cultural-related factors.In particular,sexualization of breasts as a deep-rooted belief in the Chinese context negatively affects young adults’perceptions and limits their breastfeeding practices. 展开更多

Shared Explanatory Models (EM) of High Blood Pressure (HBP)/Hypertension (HTN) were explored using systematic data collection and analysis methods from cognitive anthropology. Older adults who were members of a Medicare HMO in Los Angeles were asked to list all the illnesses experienced by older adults that they could recall, and those listing HBP or HTN were asked to further list and discuss its symptoms, causes, treatments and prevention. Responses were tape recorded, transcribed, and analyzed to develop a systematic “sentence completion by card sort” follow-up procedure. Consensus Analysis (CA) of the systematically collected data identified shared EM for HBP/HTN. The model presented here is similar to models of HBP/HTN described by researchers working with patients from different regions and different ethnic groups, suggesting that there is a widely shared lay or popular model for this disease. Stress, lifestyle (diet, exercise, weight, and substance use), heredity and aging are thought to be the major causes of HBP/HTN. Physicians are thought to be the appropriate source of care, as HTN/HBP is serious, life threatening, and potentially disabling. The study of cultural understandings and shared EM of disease has direct relevance for clinical practice and public health education. For a disease such as HTN/HBP, knowing where and how such explanations differ systematically between patients and clinicians, and what impact this may have on patterns of adherence to prescribed treatment is a crucial area of concern. 展开更多

Both Internet use’s impact on depression and urban-rural disparities related to information and communication technologies(ICTs)are crucial topics in the information systems discipline.So far,limited studies have explored these topics in a comprehensive way.This study aims to explore the impact of Internet use on urban and rural older adults’depression and provide insights into how ICTs play positive roles in human behaviors.Based on data from the China Health and Retirement Longitudinal Study,we used the panel-data regression approach to examine the relationships between older adults’Internet use and depression,and adopted the propensity score matching and the difference-in-difference approach to test the robustness of our findings.We found that the influencing mechanisms behind Internet use’s impact on urban and rural older adults’depression are different.Internet use not only directly reduces rural older adults’depression but also indirectly reduces it via the mediation of social activity,while the impact of Internet use on urban older adults’depression is fully mediated by social activity.We found that Internet use exerts different impacts on urban and rural older adults’depression,and rural older adults can receive a greater benefit. 展开更多

Purpose:To describe the development of a Compendium for estimating the energy costs of activities in adults>60 years(OA Compendium).Methods:Physical activities(PAs)and their metabolic equivalent of task(MET)values were obtained from a systematic search of studies published in 4 sport and exercise databases(PubMed,Embase,SPORTDiscus(EBSCOhost),and Scopus)and a review of articles included in the 2011 Adult Compendium that measured PA in older adults.MET values were computed as the oxygen cost(VO_(2),mL/kg/min)during PA divided by 2.7 m L/kg/min(MET_(60+))to account for the lower resting metabolic rate in older adults.Results:We identified 68 articles and extracted energy expenditure data on 427 PAs.From these,we derived 99 unique Specific Activity codes with corresponding MET_(60+)values for older adults.We developed a website to present the OA Compendium MET_(60+)values:https://pacompendium.com.Conclusion:The OA Compendium uses data collected from adults>60 years for more accurate estimation of the energy cost of PAs in older adults.It is an accessible resource that will allow researchers,educators,and practitioners to find MET_(60+)values for older adults for use in PA research and practice. 展开更多

Background:Prolonged sitting and reduced physical activity lead to low energy expenditures.However,little is known about the joint impact of daily sitting time and physical activity on body fat distribution.We investigated the independent and joint associations of daily sitting time and physical activity with body fat among adults.Methods:This was a cross-sectional analysis of U.S.nationally representative data from the National Health and Nutrition Examination Survey2011-2018 among adults aged 20 years or older.Daily sitting time and leisure-time physical activity(LTPA)were self-reported using the Global Physical Activity Questionnaire.Body fat(total and trunk fat percentage)was determined via dual X-ray absorptiometry.Results:Among 10,808 adults,about 54.6%spent 6 h/day or more sitting;more than one-half reported no LTPA(inactive)or less than 150 min/week LTPA(insufficiently active)with only 43.3%reported 150 min/week or more LTPA(active)in the past week.After fully adjusting for sociodemographic data,lifestyle behaviors,and chronic conditions,prolonged sitting time and low levels of LTPA were associated with higher total and trunk fat percentages in both sexes.When stratifying by LTPA,the association between daily sitting time and body fat appeared to be stronger in those who were inactive/insuufficiently active.In the joint analyses,inactive/insuufficiently active adults who reported sitting more than 8 h/day had the highest total(female:3.99%(95%confidence interval(95%CI):3.09%-4.88%);male:3.79%(95%CI:2.75%-4.82%))and trunk body fat percentages(female:4.21%(95%CI:3.09%-5.32%);male:4.07%(95%CI:2.95%-5.19%))when compared with those who were active and sitting less than 4 h/day.Conclusion:Prolonged daily sitting time was associated with increased body fat among U.S.adults.The higher body fat associated with 6 h/day sitting may not be offset by achieving recommended levels of physical activity. 展开更多

BACKGROUND While primary intestinal lymphangiectasia(PIL)is considered a rare condition,there have been several reported cases in adults.Nevertheless,the absence of clear guidance from diagnosis to treatment and prognosis poses challenges for both physicians and patients.AIM To enhance understanding by investigating clinical presentation,diagnosis,treatment,complications,and prognoses in adult PIL cases.METHODS We enrolled adult patients diagnosed with PIL between March 2016 and September 2021.The primary outcome involved examining the diagnosis and treatment process of these patients.The secondary outcomes included identifying complications(infections,thromboembolism)and assessing prognoses(frequency of hospitalization and mortality)during the follow-up period.RESULTS Among the 12 included patients,peripheral edema(100%)and diarrhea(75%)were the main presenting complaints.Laboratory tests showed that all the pati-ents exhibited symptoms of hypoalbuminemia and hypogammaglobulinemia.Radiologically,the predominant findings were edema of the small intestine(67%)and ascites(58%).The typical endoscopic finding with a snowflake appearance was observed in 75%of patients.Among the 12 patients,two responded positive-ly to octreotide and sirolimus,and eight who could undergo maintenance therapy discontinued subsequently.Complications due to PIL led to infection in half of the patients,thromboembolism in three patients,and one death.CONCLUSION PIL can be diagnosed in adults across various age groups,with different severity and treatment responses among patients,leading to diverse complications and prognoses.Consequently,tailored treatments will be necessary.We anticipate that our findings will contribute to the management of PIL,an etiology of protein-losing enteropathy. 展开更多

Background:Emerging adulthood is a pivotal life stage,presenting significant psychological and social changes,such as decreased sociability,depression,and other mental health problems.Previous studies have associated these changes with an unhealthy lifestyle.The 24-h movement guidelines for healthy lifestyles have been developed to promote appropriate health behaviors and improve individual wellness.However,the relationship between adherence to the 24-h movement guidelines and different characteristics of Chinese emerging adults is yet to be explored.This cross-sectional study aimed to investigate the association between adherence to the 24-h movement guidelines and four characteristics(self-exploration,instability,possibilities,and responsibility)of Chinese emerging adults.Methods:Overall,1,510 Chinese emerging adults aged 18–29 years were included in this study.Each participant completed a self-administered questionnaire that included questions on adherence to the 24-h movement guidelines(physical activity,sedentary behavior,and sleep)and the inventory of dimensions of emerging adulthood.Multivariable logistic regression analysis was employed to investigate the associations between adherence to the 24-h movement guidelines and each of the four characteristics.Results:The proportion of participants who adhered to the 24-h movement guidelines was 31.72%.Multiple regression analysis revealed a significantly negative relationship between adhering to more guidelines and instability(β=−0.51,p<0.001).A statistically significant association was observed between instability and meeting only sedentary behavior(β=−1.27,95%confidence interval[CI]:[−2.32,−0.24],p=0.02),sedentary behavior+sleep(β=−1.30,95%CI:[−2.24,−0.35],p<0.01),and physical activity+sedentary behavior(β=−1.08,95%CI:[1.94,−0.21],p=0.02)guidelines.Further,positive and significant associations were observed between possibilities and meeting the guidelines for only physical activity(β=0.70,95%CI:[0.14,1.27),p=0.01),only sleep(β=0.61,95%CI:[0.01,1.21],p=0.04),physical activity+sedentary behavior(β=0.56,95%CI:[0.04,1.07),p=0.01),and physical activity+sleep(β=0.76,95%CI:[0.23,1.27],p=0.01).Conclusions:These findings suggest that adherence to the 24-h movement guidelines was associated with instability in Chinese emerging adults.Future studies are warranted to verify our findings to highlight the importance of maintaining a heath lifestyle to promote health in emerging adulthood. 展开更多

Objective This study aimed to explore the relationships between residential greenness and cardiometabolic risk factors among rural adults in Xinjiang Uygur Autonomous Region(Xinjiang)and thus provide a theoretical basis and data support for improving the health of residents in this region.Methods We recruited 9,723 adult rural residents from the 51st Regiment of the Third Division of the Xinjiang Production and Construction Corps in September 2016.The normalized difference vegetation index(NDVI)was used to estimate residential greenness.The generalized linear mixed model(GLMM)was used to examine the association between residential greenness and cardiometabolic risk factors.Results Higher residential greenness was associated with lower cardiometabolic risk factor prevalence.After adjustments were made for age,sex,education,and marital status,for each interquartile range(IQR)increase of NDVI500-m,the risk of hypertension was reduced by 10.3%(OR=0.897,95%CI=0.836-0.962),the risk of obesity by 20.5%(OR=0.795,95%CI=0.695-0.910),the risk of type 2 diabetes by 15.1%(OR=0.849,95%CI=0.740-0.974),and the risk of dyslipidemia by 10.5%(OR=0.895,95%CI=0.825-0.971).Risk factor aggregation was reduced by 20.4%(OR=0.796,95%CI=0.716-0.885)for the same.Stratified analysis showed that NDVI500-m was associated more strongly with hypertension,dyslipidemia,and risk factor aggregation among male participants.The association of NDVI500-m with type 2 diabetes was stronger among participants with a higher education level.PM10 and physical activity mediated 1.9%-9.2%of the associations between NDVI500-m and obesity,dyslipidemia,and risk factor aggregation.Conclusion Higher residential greenness has a protective effect against cardiometabolic risk factors among rural residents in Xinjiang.Increasing the area of green space around residences is an effective measure to reduce the burden of cardiometabolic-related diseases among rural residents in Xinjiang. 展开更多

BACKGROUND Hepatobiliary and pancreatic(HBP)cancers impose a considerable burden on young populations(aged 15 to 49 years),resulting in a substantial number of new cases and fatalities each year.In young populations,the HBP cancers shows extensive variance worldwide and the updated data in China is lacking.AIM To investigate the current status,trends,projections,and underlying risk factors of HBP cancers among young populations in China.METHODS The Global Burden of Disease Study 2019 provided data on the annual incidence,mortality,disability-adjusted life years(DALYs),age-standardized incidence rate(ASIR),mortality rate(ASMR),and DALYs rate(ASDR)of HBP cancers in young Chinese adults between 1990 and 2019.Temporal trends were assessed using estimated annual percentage change and hierarchical clustering.Sex-specific mortality and DALYs caused by various risks were analyzed across China and other regions,with future trends until 2035 projected using the Bayesian age-period-cohort model.RESULTS From 1990 to 2019,incident cases,deaths,DALYs,ASIR,ASMR,and ASDR for liver cancer(LC)in young Chinese individuals decreased,classified into'significant decrease'group.Conversely,cases of gallbladder and biliary tract cancer and pancreatic cancer rose,categorized as either'significant increase'or'minor increase'groups.The contribution of risk factors to mortality and DALYs for HBP tumors increased to varying degrees.Healthy lifestyle behaviors,such as tobacco control,weight management,alcohol moderation,and drug avoidance,could lower HBP cancers incidence.Moreover,except for LC in females,which is likely to initially decline slightly and then rise,the forecasting model predicted that the ASIR and ASMR for all HPB cancers subtypes by gender will increase among young adults.CONCLUSION HBP cancers burden among young adults in China is expected to increase until 2035,necessitating lifestyle interventions and targeted treatment strategies to mitigate the public health impact of these cancers. 展开更多

BACKGROUND Frailty is a complex aging-related syndrome characterized by a cumulative loss of physiological reserve and increased vulnerability to adverse clinical outcomes,including falls,disability,incapacity and death.While an increasing number of studies suggest that the gut microbiota may play a key role in the pathophy-siology of frailty,direct evaluation of the association between gut microbiome alterations and frailty in older adults remains limited.AIM Seven electronic databases(China National Knowledge Infrastructure,VIP,SinoMed,Wanfang,PubMed,Web of Science and EMBASE)were searched for articles published before October 31,2023 to identify observational studies that compared the microbiomes of older adults with and without frailty.The diversity and composition of the gut microbiota were the main outcomes used to analyze the associations of changes in the gut microbiota with frailty in older adults.The quality of the included studies was assessed via the Newcastle-Ottawa Scale and the Agency for Healthcare Research and Quality.RESULTS Eleven observational studies with 912 older adults were included in this review.Consistent results revealed a significant difference in the gut microbiota composition between frail and non-frail older adults,with a significant decrease inαdiversity and a significant increase inβdiversity in frail older adults.The pooled results revealed that at the phylum level,four microbiota(Actinobacteria,Proteo-bacteria,Verrucomicrobia and Synergistetes)were significantly enriched,and two microbiota(Firmicutes and Fusobacteria)were significantly depleted in frail older adults.At the family level,the results consistently revealed that the abundances of 6 families,most of which belong to the Actinobacteria or Proteo-bacteria phylum,were greater in frail than in non-frail older adults.At the genus or species level,consistent results from more than two studies revealed that the abundances of the genera Prevotella,Faecalibacterium,and Roseburia were significantly lower in frail older adults;individual studies revealed that the abundances of some genera or species(e.g.,Megamonas,Blautia,and Megasphaera)were significantly lower,whereas those of other genera or species(e.g.,Bifidobacterium,Oscillospira,Ruminococcus and Pyramidobacter)were significantly greater in frail older adults.CONCLUSION This systematic review suggests that changes in the gut microbiota are associated with frailty in older adults,which is commonly reflected by a reduction in beneficial species and an increase in pathogenic species.However,further studies are needed to confirm these findings. 展开更多

BACKGROUND Major depressive disorder(MDD)in adolescents and young adults contributes significantly to global morbidity,with inconsistent findings on brain structural changes from structural magnetic resonance imaging studies.Activation likeli-hood estimation(ALE)offers a method to synthesize these diverse findings and identify consistent brain anomalies.METHODS We performed a comprehensive literature search in PubMed,Web of Science,Embase,and Chinese National Knowledge Infrastructure databases for neuroi-maging studies on MDD among adolescents and young adults published up to November 19,2023.Two independent researchers performed the study selection,quality assessment,and data extraction.The ALE technique was employed to synthesize findings on localized brain function anomalies in MDD patients,which was supplemented by sensitivity analyses.RESULTS Twenty-two studies comprising fourteen diffusion tensor imaging(DTI)studies and eight voxel-based morphome-try(VBM)studies,and involving 451 MDD patients and 465 healthy controls(HCs)for DTI and 664 MDD patients and 946 HCs for VBM,were included.DTI-based ALE demonstrated significant reductions in fractional anisotropy(FA)values in the right caudate head,right insula,and right lentiform nucleus putamen in adolescents and young adults with MDD compared to HCs,with no regions exhibiting increased FA values.VBM-based ALE did not demonstrate significant alterations in gray matter volume.Sensitivity analyses highlighted consistent findings in the right caudate head(11 of 14 analyses),right insula(10 of 14 analyses),and right lentiform nucleus putamen(11 of 14 analyses).CONCLUSION Structural alterations in the right caudate head,right insula,and right lentiform nucleus putamen in young MDD patients may contribute to its recurrent nature,offering insights for targeted therapies. 展开更多

BACKGROUND Diabetes is a chronic metabolic syndrome that has become a global public health problem with significant morbidity and mortality.It is a pro-inflammatory and pro-thrombotic condition characterized by increased platelet activation and alterations in platelet indices.However,the use of platelet indices as predictors of poor glucoregulation has not been fully evaluated in this context,and evidence for their role as predictors of poor glycemic status in diabetic patients is limited.AIM To evaluate platelet indices and determine their prognostic significance in relation to inadequate glucoregulation among individuals diagnosed with type 2 diabetes at Bishoftu General Hospital in Ethiopia,from June 15 to August 12,2022.METHODS A comparative cross-sectional study was conducted in 261 participants including 174 individuals with type 2 diabetes mellitus(T2DM)and 87 non-diabetic controls.The systematic random sampling technique was used to select participants.Data were collected using structured questionnaires,physical measurements,checklists,and laboratory tests.Platelet parameters and fasting blood glucose levels were determined from blood samples using Sysmex-XN550 and CobasC311 analyzers,respectively.The hematology analyzer output was checked and participants were also screened for malaria parasites using a prepared blood smear.Collected data were entered into Epi-data version 3.1 and exported to SPSS version 25 for analysis.Theχ^(2) test,Mann-Whitney U test,Kruskal-Wallis test,post hoc test,Spearman correlation,and receiver operating characteristic curve were used for analysis.A P value<0.05 was considered statistically significant.RESULTS The results of our study indicate that diabetic patients have significantly higher levels of platelet distribution width(PDW),mean platelet volume(MPV),platelet large cell ratio(PLCR),and plateletcrit(PCT)compared to healthy individuals(P<0.001).Furthermore,these indices were found to be significantly elevated in individuals with poor glycemic control in T2DM compared to those with good glycemic control and healthy controls.We also observed significant correlations between these indices and various anthropometric and clinical variables.Our findings suggest that PDW,with a cut-off value of 15.75 fL and an area under the curve(AUC)of 0.803,MPV,with a cut-off value of 12.25 fL and an AUC of 0.774,PLCR,with a cut-off value of 36.3%and an AUC of 0.775,and PCT,with a cut-off value of 0.24%and an AUC of 0.761,can serve as predictors of poor glycemic control in patients with diabetes mellitus.CONCLUSION The observed correlation between diabetic patients and a significant increase in platelet indices has highlighted their potential as predictors of poor glycemic control in diabetes.Therefore,regular screening and profiling of platelet indices is recommended as part of the follow-up process for individuals with diabetes mellitus. 展开更多

Social determinants of health(SDOH)affect quality of life.We investigated SDOH impacts on self-perceived resilience among people with adult congenital heart disease(ACHD).Secondary analysis of data from two com-plementary studies:a survey study conducted May 2021–June 2022 and a qualitative study conducted June 2020–August 2021.Resilience was assessed through CD-RISC10 score(range 0–40,higher scores reflect greater self-perceived resilience)and interview responses.Sociodemographic and SDOH(education,employment,living situa-tion,monetary stability,financial dependency,area deprivation index)data were collected by healthcare record review and self-report.We used linear regression with robust standard errors to analyze survey data and performed a thematic analysis of interview data.Survey participants(N=127)mean age was 42±14 years;51%were female,87%white.ACHD was moderate(75%)or complex(25%);41%functional class C or D.Resilience(mean 30±7)varied by monetary stability:compared to people with difficulty paying bills,resilience was 15.0 points higher(95%CI:6.9–23.1,p<0.001)for people reporting having enough money and 14.2 points higher(95%CI:5.9–22.4,p=0.001)for those reporting just enough money.Interview participants’(N=25)mean age was 32 years(range 22–44);52%were female,72%white.ACHD was moderate(56%)or complex(44%);76%functional class C or D.Participants discussed factors affecting resilience aligned with each of the major SDOH,prominently,economic stability and healthcare access and quality.Financial stability may be important for supporting self-perceived resi-lience in ACHD.This knowledge can inform the development of resilience interventions for this population. 展开更多

Blastomas,characterized by a mixture of mesenchymal,epithelial,and undifferentiated blastematous components,are rare malignant neoplasms originating from precursor blast cells.This review focuses on digestive system blastomas in adult patients,including gastroblastoma,hepatoblastoma,and pancreatoblastoma.Gastroblastoma is a biphasic,epitheliomesenchymal tumor,with only sixteen cases reported to date.In addition to the characteristic histology,metastasisassociated lung adenocarcinoma transcript 1-glioma-associated oncogene homolog 1 gene fusion is typical,although recently novel ewing sarcoma breakpoint region 1-c-terminal binding protein 1 and patched 1-glioma-associated oncogene homolog 2 fusions have been described.Hepatoblastoma is exceptionally rare in adults and can show a variety of histologic patterns which may cause diagnostic difficulty.Pancreatoblastoma,primarily a pediatric tumor,displays acinar differentiation and squamoid nests with other lines of differentiation also present,especially neuroendocrine.Diagnostic approaches for these blastomas include a combination of imaging modalities,histopathological examination,and molecular profiling.The treatment generally involves surgical resection,which may be supplemented by chemotherapy or radiotherapy in some cases.Prognoses vary with gastroblastoma generally showing favorable outcomes post-surgery whereas hepatoblastoma and pancreatoblastoma often have poorer outcomes,particularly in the setting of metastases.This review highlights the complexity of diagnosing and managing these rare adult blastomas as well as the need for ongoing research to better understand their pathogenesis and improve treatment strategies. 展开更多

Background:Much has been written about the loss to follow-up in the transition between pediatric and adult Congenital Heart Disease(CHD)care centers.Much less is understood about the loss to follow-up(LTF)after a successful transition.This is critical too,as patients lost to specialised care are more likely to experience mor-bidity and premature mortality.Aims:To understand the prevalence and reasons for loss to follow-up(LTF)at a large Australian Adult Congenital Heart Disease(ACHD)centre.Methods:Patients with moderate or highly complex CHD and gaps in care of>3 years(defined as LTF)were identified from a comprehensive ACHD data-base.Structured telephone interviews examined current care and barriers to clinic attendance.Results:Overall,407(22%)of ACHD patients(n=1842)were LTF.The mean age at LTF was 31(SD 11.5)years and 54%were male;311(76%)were uncontactable.Compared to adults seen regularly,lost patients were younger,with a greater socio-economic disadvantage,and had less complex CHD(p<0.05 for all).We interviewed 59 patients(14%).The top 3 responses for care absences were“feeling well”(61%),losing track of time(36%),and not needing fol-low-up care(25%).Conclusions:A large proportion of the ACHD population becomes lost to specialised cardiac care,even after a successful transition.This Australian study reports younger age,moderate complexity defects,and socio-economic disadvantage as predictive of loss to follow-up.This study highlights the need for novel approaches to patient-centered service delivery even beyond the age of transition and resources to maintain patient engagement within the ACHD service. 展开更多
